We recommend you acquire a USB drive with a USB-C connector. That’s the reason why we wrote a post on how to burn ISO to USB on Mac if you are searching for an solution to create bootable USB from ISO image.īefore we begin, make sure you now have a USB flash drive. The situation becomes even harder on latest macOS Big Sur as some of the existing apps such as UNetbootin still does add support for Big Sur. The fact is that there are dozens of free tools available on Windows, but it is not easy to get one on Mac (mostly are for DVD burning).

I tried your approach just from the command line with:ĭiskName=$(drutil status | grep 'Name:' | awk ' If anyone knows how to determine the disk number in the script to get around this caveat, then I think we have a complete solution. Personally, I mount all my drives first, then pop the CD/DVD in and I know it will always be disk4 (on my system).

The only caveat is that you must have the same drives mounted when you run the script as you did when you issued the drutil status command, otherwise the disk number of the CD/DVD drive will be different and the whole thing won't work for you. When you run the script, you will see your CD/DVD unmount then you will know the process is finished as the CD/DVD will be remounted again. Save the script somewhere and voila, you have a green button method of creating iso's and you only had to type the shell commands once. You'll probably see an example command 'cat' in there already, delete this and type:ħ. On the left hand side you will see all the applications you have on your system that can be scripted - select Automator from here and then drag 'Run Shell Script' to the right hand pane.Ħ. Therefore when I run drutil status i get /dev/disk4 as the name of the current CD/DVD.ĥ. On my system, I have one internal HD and 3 external HD's. Make a note of the Name (something like /dev/disk1) - the drive number changes according to what disks you have mounted at the time you issue the command. Open Terminal and run the command: drutil statusģ. If you are using Tiger, you can very easily create a shell script in automator to have a 'green button' version of tgage's solution.Ģ.
